Temperature
The temperature grades are A Ð the
highest Ð, B, and C, representing the tire's
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A repre-
sent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.<
Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to page 193.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tire tread
The tread depth should not fall below e in/
3 mm.
At tread depths below e in/3 mm, there is
an increased risk of high-speed hydroplan-
ing, even when only small amounts of
water are present on the road surface.As winter tires display a noticeable loss in
their ability to cope with cold-weather driv-
ing conditions once the tread wears to
below k/K in/4 mm, to ensure continued
safety you should always have such tires
replaced.
Wear indicators at the tread-groove base,
refer to arrow, are distributed over the tire's
circumference and are marked on the side
of the tire with TWI Ð Tread Wear Indicator.
These indicators signal at a tread depth
of k/FK in/1.6 mm that the legally permitted
wear limit has been reached.
Tire damage
Unusual vibrations encountered dur-
ing normal vehicle operation can
indicate tire failure or some other vehicle
defect. This can, for example, be caused
by driving over curbs.
These kinds of problems may also be
signaled by other changes in vehicle
response, such as a strong tendency to
pull to the left or right. Should this occur,
respond by immediately reducing your
speed. Carefully proceed Ð or have your
vehicle towed Ð to the nearest BMW center
or tire dealer to have the wheels or tires
inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal safety
hazard for the vehicle's occupants and
other road users alike.<

Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation
pressure indicated on the side wall of the
tire.
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to
a restricted degree.
If you switch from summer to winter
tires, or vice versa, use run-flat tires,
as in the event of a breakdown there is no
spare wheel available. In this case, BMW
recommends that you consult your BMW
center. Your BMW center is qualified to
handle run-flat tires and equipped with the
necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue,
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h.
In the case of complete inflation pressure
loss, 0 psi/kPa, or obvious tire damage,
you can estimate the possible distance for continued driving on the basis of the fol-
lowing guide values:
>With low load:
1 to 2 persons without luggage:
Approx. 150 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
More than 4 persons, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. With
inflation pressure loss, the driving charac-
teristics change, for example reduced track
stability on braking, extended braking dis-
tance, and altered self-steering character-
istics.<
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels,
and should only be mounted on tires
with the dimensions 245/50 R 18. Observe
the manufacturer's instructions when
installing snow chains.Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 93.<

Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature 3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.

Antifreeze and anticorrosion agents are
flammable. Therefore, do not pour over hot
engine parts, as otherwise they could catch
fire and cause burns.
Always observe the instructions for use
provided on the containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
Checking coolant level
Correct coolant level with the engine cold Ð
approx. +687/206:
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler
neck
3.If the coolant is low, slowly add coolant
up to the specified level Ð do not overfill.
Brake fluid
The symbol lights up and a mes-
sage appears in the Check Control:
The brake fluid in the reservoir has
fallen to below the minimum level.
The brake fluid reservoir is located under
the microfilter housing trim panel on the
driver's side of the vehicle. To have brake
fluid added to the system, or to have the source of any brake fluid loss traced and
rectified, please contact your BMW center,
which can also supply the factory-
approved Ð DOT 4 Ð brake fluids.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time.
To ensure that the brake system continues
to provide safe and reliable performance,
remember to have the brake fluid changed
every two years at the latest, refer to
page 82 and to the Service and Warranty
Information Booklet for US models or the
Warranty and Service Guide Booklet for
Canadian models.
Brake fluid is toxic and also damages vehi-
cle paintwork. Always store these agents in
tightly-closed original containers kept well
away from the reach of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. Should it come into contact with hot
engine components, the brake fluid could
ignite and cause personal injury in the form
of burns.<
Always observe all applicable envi-
ronmental rules and regulations when
disposing of used brake fluid.<
Warning lamp for Canadian models.
Brake hydraulic systems
A low brake-fluid level combined with
longer-than-usual pedal travel could be
a sign that one of the brake system's
hydraulic circuits has failed.
Proceed to the nearest BMW center.
Remember that pedal travel may be
increased, and there may also be a sub-
stantial increase in the amount of pedal
pressure required to brake the vehicle.
Please adapt your driving style accord-
ingly.<

Rules and regulations
California Proposition 65
Warning
California laws require us to issue the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory animals.
Always protect your skin by washing thor-
oughly with soap and water.<
OBD connector
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side under the instrument panel and under
a cover.
The cover has the letters OBD on it.The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deterioration
and malfunction.
An indicator lamp informs you of the
need for service, not of the need to
stop the vehicle. However, the sys-
tems should be checked by your BMW
center at the earliest possible opportunity.
Indicator lamp for Canadian mod-
els.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a
rather severe level of engine misfire. When
this occurs, you should reduce speed and
consult the nearest BMW center as soon as
possible. Severe engine misfire over only a
short period of time can seriously damage
emissions control components, especially
the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator will
light up. If the filler cap is subsequently
tightened, the indicator lamp should go out
within a few days.<

Change the wheel only on a level, firm sur-
face which is not slippery. The vehicle or
the jack could slip to the side if you attempt
to raise the vehicle on a soft or slippery sur-
face such as snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-car-
rying capacity.
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
